Specifically, we investigated the Iambic/Trochaic Law, an assumed universal grouping bias, in simultaneous French-German bilinguals, presenting them with streams of syllables varying in intensity, duration or neither and asking them whether they perceived them as strong-weak or weak-strong groupings. Results showed robust, consistent grouping preferences. A comparison to monolinguals from previous studies revealed that they pattern with German-speaking monolinguals, and differ from French-speaking monolinguals. The distribution of simultaneous bilinguals' individual performance was best explained by a model fitting a unimodal (not bimodal) distribution, failing to support two subgroups of language dominance. Moreover, neither language experience nor language context predicted their performance. These findings suggest a special role for universal biases in simultaneous bilinguals.}, language = {en} } @article{BhataraBollAvetisyanUngeretal.2013, author = {Bhatara, Anjali and Boll-Avetisyan, Natalie and Unger, Annika and Nazzi, Thierry and H{\"o}hle, Barbara}, title = {Native language affects rhythmic grouping of speech}, series = {The journal of the Acoustical Society of America}, volume = {134}, journal = {The journal of the Acoustical Society of America}, number = {5}, publisher = {American Institute of Physics}, address = {Melville}, issn = {0001-4966}, doi = {10.1121/1.4823848}, pages = {3828 -- 3843}, year = {2013}, abstract = {Perceptual attunement to one's native language results in language-specific processing of speech sounds. This includes stress cues, instantiated by differences in intensity, pitch, and duration. The present study investigates the effects of linguistic experience on the perception of these cues by studying the Iambic-Trochaic Law (ITL), which states that listeners group sounds trochaically (strong-weak) if the sounds vary in loudness or pitch and iambically (weak-strong) if they vary in duration. Participants were native listeners either of French or German; this comparison was chosen because French adults have been shown to be less sensitive than speakers of German and other languages to word-level stress, which is communicated by variation in cues such as intensity, fundamental frequency (F0), or duration. In experiment 1, participants listened to sequences of co-articulated syllables varying in either intensity or duration. The German participants were more consistent in their grouping than the French for both cues. Experiment 2 was identical to experiment 1 except that intensity variation was replaced by pitch variation. German participants again showed more consistency for both cues, and French participants showed especially inconsistent grouping for the pitch-varied sequences. These experiments show that the perception of linguistic rhythm is strongly influenced by linguistic experience.}, language = {en} } @article{vanOmmenBollAvetisyanLarrazaetal.2020, author = {van Ommen, Sandrien and Boll-Avetisyan, Natalie and Larraza, Saioa and Wellmann, Caroline and Bijeljac-Babic, Ranka and H{\"o}hle, Barbara and Nazzi, Thierry}, title = {Language-specific prosodic acquisition}, series = {Journal of memory and language: JML}, volume = {112}, journal = {Journal of memory and language: JML}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0749-596X}, doi = {10.1016/j.jml.2020.104108}, pages = {16}, year = {2020}, abstract = {This study compares the development of prosodic processing in French- and German-learning infants. The emergence of language-specific perception of phrase boundaries was directly tested using the same stimuli across these two languages. French-learning (Experiment 1, 2) and German-learning 6- and 8-month-olds (Experiment 3) listened to the same French noun sequences with or without major prosodic boundaries ([Loulou et Manou] [et Nina]; [Loulou et Manou et Nina], respectively). The boundaries were either naturally cued (Experiment 1), or cued exclusively by pitch and duration (Experiment 2, 3). French-learning 6- and 8-month-olds both perceived the natural boundary, but neither perceived the boundary when only two cues were present. In contrast, German-learning infants develop from not perceiving the two-cue boundary at 6 months to perceiving it at 8 months, just like German-learning 8-month-olds listening to German (Wellmann, Holzgrefe, Truckenbrodt, Wartenburger, \& Hohle, 2012). In a control experiment (Experiment 4), we found little difference between German and French adult listeners, suggesting that later, French listeners catch up with German listeners. Taken together, these cross-linguistic differences in the perception of identical stimuli provide direct evidence for language-specific development of prosodic boundary perception.}, language = {en} } @article{HoehleBijeljacBabicHeroldetal.2009, author = {H{\"o}hle, Barbara and Bijeljac-Babic, Ranka and Herold, Birgit and Weissenborn, J{\"u}rgen and Nazzi, Thierry}, title = {Language specific prosodic preferences during the first year of life : evidence from German and French infants}, issn = {0163-6383}, doi = {10.1016/j.infbeh.2009.03.004}, year = {2009}, language = {en} } @article{BhataraBollAvetisyanAgusetal.2016, author = {Bhatara, Anjali and Boll-Avetisyan, Natalie and Agus, Trevor and H{\"o}hle, Barbara and Nazzi, Thierry}, title = {Language Experience Affects Grouping of Musical Instrument Sounds}, series = {Cognitive science : a multidisciplinary journal of anthropology, artificial intelligence, education, linguistics, neuroscience, philosophy, psychology ; journal of the Cognitive Science Society}, volume = {40}, journal = {Cognitive science : a multidisciplinary journal of anthropology, artificial intelligence, education, linguistics, neuroscience, philosophy, psychology ; journal of the Cognitive Science Society}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0364-0213}, doi = {10.1111/cogs.12300}, pages = {1816 -- 1830}, year = {2016}, language = {en} } @article{GonzalezGomezSchmandtFazekasetal.2018, author = {Gonzalez-Gomez, Nayeli and Schmandt, Silvana and Fazekas, Judit and Nazzi, Thierry and Gervain, Judit}, title = {Infants' sensitivity to nonadjacent vowel dependencies}, series = {Journal of experimental child psychology}, volume = {178}, journal = {Journal of experimental child psychology}, publisher = {Elsevier}, address = {New York}, issn = {0022-0965}, doi = {10.1016/j.jecp.2018.08.014}, pages = {170 -- 183}, year = {2018}, abstract = {Vowel harmony is a linguistic phenomenon whereby vowels within a word share one or several of their phonological features, constituting a nonadjacent, and thus challenging, dependency to learn. It can be found in a large number of agglutinating languages, such as Hungarian and Turkish, and it may apply both at the lexical level (i.e., within word stems) and at the morphological level (i.e., between stems and their affixes). Thus, it might affect both lexical and morphological development in infants whose native language has vowel harmony. The current study asked at what age infants learning an irregular harmonic language, Hungarian, become sensitive to vowel harmony within word stems. In a head-turn preference study, 13-month-old, but not 10-month-old, Hungarian-learning infants preferred listening to nonharmonic VCV (vowel-consonant-vowel) pseudowords over vowel harmonic ones. A control experiment with 13-month-olds exposed to French, a nonharmonic language, showed no listening preference for either of the sequences, suggesting that this finding cannot be explained by a universal preference for nonharmonic sequences but rather reflects language-specific knowledge emerging between 10 and 13 months of age. We discuss the implications of this finding for morphological and lexical learning. (C) 2018 Published by Elsevier Inc.}, language = {en} }
